Patch to test for KeyboardInterrupt

GDB does not pass the KeyboardInterrupt exception to Python when the user
terminates paged terminal output generated by Python.  This causes Python
scripts to terminate when the user interrupts output.  

(gdb) set height 5
(gdb) python
>try:
>    for i in range(400):
>        print i
>except KeyboardInterrupt:
>    print "caught interrupt"
>end

Quit


When the output is generated by a GDB command, the exception is caught and
passed to Python.

(gdb) python
>try:
>    gdb.execute("help all")
>except KeyboardInterrupt:
>    print "caught interrupt"
>end

Command class: aliases
